I noticed a small error, though I don't know if it's on the headstone or the transcription. The record for "Bickford, Julia" goes on to say that she was the daughter of Azariah Munden. Indeed she was--her name was Julia Bickford Munden, and as far as I know she never married. Since her grandmother's name was Julia
Bickford, and she had an aunt named Julia Bickford Henley (all from Devon, England) I think it unlikely she got the name by marrying a Bickford in Harbour Grace or Brigus.
